Profiling Long-Distance Urban Near-Surface Structures with Temporary Fiber-Optic Sensing in Jinan City, China [PDF]
SensorsFine-scale urban underground exploration is vital for geological safety and hydrogeological protection. In spring-rich cities like Jinan, shallow structures—such as sedimentary layers and fault systems—act as critical regulators of groundwater migration ...

Earthquake Risk Assessment for Tehran, Iran [PDF]
ISPRS International Journal of Geo-Information, 2020 The megacity of Tehran, the capital of Iran, is subjected to a high earthquake risk. Located at the central part of the Alpine–Himalayan seismic belt, Tehran is surrounded by several active faults that show some M7+ historical earthquake records. The high seismic hazard in combination with a dense population distribution and several vulnerability ...

Who Is at Risk of Death in an Earthquake? [PDF]
American Journal of Epidemiology, 2004 Although, theoretically, the impacts of a disaster are not randomly distributed across health and socioeconomic classes, empirical evidence of this claim is scarce. In a population-based cohort study, the authors identified risk factors for mortality from the September 21, 1999, Taiwan earthquake, which occurred in the middle of the night.

Liquidity Risks and Demands for Earthquake Insurances
2005 IEEE International Conference on Systems, Man and Cybernetics, 2005 本研究では危険中立的な企業の地震保険保有行動を流動性需要に基づいて説明する. 具体的には, 企業の地震保険保有行動を借入制約を考慮した3期間モデルを用いて定式化する. 企業が初期投資を実施し, その収益を回収するまでの期間内に地震が発生した場合, 企業は緊急に流動性資産を調達する必要がある. しかし, 企業が負債を抱えている場合, 追加融資の調達が困難になる過重債務問題が発生する可能性がある. 地震保険は, 地震発生時に生じる過重債務問題を克服するための手段になる. さらに, 地震保険保有により生じるモラルハザード問題を分析し, モラルハザードと過重債務問題を同時に克服しうるファイナイト契約について考察する.
